~GTOs (Gate Turn-off Thyristors) are optimized for low
conduction losses. The typical on-off switching frequency is in the
range of **0 - **0 hertz for most applications. GTOs are, by
nature, relatively slow switches. Typical transition times from on
to off state and vice versa are in a range of *0 - *0 microseconds.
All GTOs require protective networks called "snubbers" for turn-on
and turn-off. The turn-on snubber circuit, in essence an inductor,
limits the rate of current rise. For turn-off, the GTO requires a
device that limits the rate of voltage rise, in essence a
capacitor.
All ABB GTOs are press-pack devices. They are pressed with a
relatively high force onto heat-sinks which also serve as
electrical contacts to the power terminals.
Asymmetric GTOs are divided in two categories: Buffer layer and
Standard. Buffer layer GTOs have exceptionally low on-state and
dynamic losses. Fine pattern types (5SGF) are optimised for fast
switching and transparent emitter (5SGT) for low on-state losses.
The Standard GTOs have excellent trade-off between on-state and
switching losses.
